IMPROVEMENT IN HAND-POWERS FOR OPERATING CHURNS, 800.

Specification forming part of Letters Patent No. 217.892, dated July 29,1879; application filed June 10, 1879.

To all whom it may concern Be it known that I, JAMES W. MILLER, of NewCastle, in the county of Lawrence and State of Pennsylvania, haveinvented certain new and useful Improvements in Hand-Powers forOperating Ohurns, &c.; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains, to make and use thesame, reference being had to the accompanying drawin gs, and to lettersof reference marked thereon, which form a part of this specification.

My invention relates to improvements in hand-powers for operatingchurns, Ste. and it consists in the novel construction and arrangementof the various parts, all of which will be hereinafter more fullydescribed.

The annexed drawings, to which reference is made, fully illustrate myinvention, in which Figure 1 represents a side view of my improvedhand-power applied to a churn. Fig. 2 represents an end view of thesame. Fig. 3 is a detail view.

A A represent vertical standards, having abase or feet, a a, upon whichthe same is supported. Said standards are connected to one another bymeans of bolts a a and a bolt,

' a, in the upper end of the standards A A.

B represents a fly -wheel, journaled to the standard A, and between saidstandard and the opposite standard, A, and is connected to a horizontallever, O, by a rod or pitman, 0, one end of which is pivoted to thefly-wheel B at b, and the upper end thereof is pivoted to the lever O atc. Said lever O is provided with a perforation, through which passes thebolt a and has on each side thereof washers c c and pins 0 0 for keepingthe lever G in place. The short arm 0 of said lever is connected to ahand-lever, D, by means of a rod, (1, pivoted to said arm 0 at a" andthe handlever D at (1. The lever D is pivoted at its inner end to theinside of the standard A at (P, and has on its opposite end a handle, dby which the same is operated.

A guide, E, in the form of the letter U, is fixed to the standards A A,through which the lever G moves and the latter is guided and kept fromlateral motion.

The forward end of the lever C may be constructed with a vertical slot,in which is pivoted at its upper end a swinging arm, the lower end ofwhich is provided with an eye, for the purpose of receiving the upperportion of a dash-rod, and the same being secured thereto by means of apin running crosswise the same, or a thumb-screw, as shown in Fig. 3 ofthe drawings.

Having described the differentparts of which my churn-power isconstructed, I will now proceed and give the mode in which it isoperated.

Operation: The handle al on the lever D is given a vertical movement bythe operator, and turns on its pivoted end a thus communicating motionto the lever G by the rod (1, pivoted to the same and the hand-lever D.Motion is then given to the fly-wheel B through the medium of thepitman-rod 0, connected to said lever G and the fly-wheel B. The forwardend of the lever (J is thus given an upand-down or vertical movement, bymeans of which a churn or other like article can be operated.

In the drawings 'I have shown the levers O D, rod (1, and pitman rod 0connected to one another, as well as the fly-wheel, by holes orperforations, for regulating the length of the stroke and the speed ofthe fly-wheel, but reserve the right to connect the various partstogether by means of sliding bolts passing through slots made in thestandards A A, fly -wheel B, and levers O, and D, by means of which therevolution of the fly-wheel B can be regulated to a desired speed; also,I construct the tly-wheel B with one side somewhat heavier than theother, in order to overcome a dead-center, to which the same is liableotherwise.

Furthermore, a belt may be applied to the fly-wheel B, as shown in Fig.1 of the drawings, for operating fly-fans and other light maehinery.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The churn-power constructed as herein described, consisting of the mainstandards A A, base a a, and bolts a a the hand lever D, lever O, pitmenc d, guide E, and fly-wheel B, as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this7th day of June, 1879.
